Hish speed deep packet inspection method with low power dissipation by ZHU Guo-sheng1, YU Shao-hua1

“…Hish speed deep packet inspection using TCAM faces the problem of high power dissipation.A 2-phase DPI method BF-TCAM was proposed.The first phase used parallel Bloom filters to exclude the normal packets not including attack signatures.The second phase used TCAM to inspect suspicious packets including real attack packets and false positive packets of the first phase.The Bloom filters’ false negative probability is zero and false positive probability is very low.Since most of the network data traffic does not include attack signatures,the method can get high speed deep packet inspection with low power dissipation.…”

Traffic measurement algorithm based on least recent used and Bloom filter by Zhen ZHANG, Bin-qiang WANG, Feng-yu ZHANG, Ning-ning LIANG

“…Aiming at the naïve algorithm’s deficiency of high false negative probability,a novel scheme called LRU-BF(least recent used ＆amp;Bloom filter) was presented.In order to achieve high accuracy,the algorithm adopted mechanisms of LRU eliminating and Bloom filter representation to separate the process of heavy-hitter fliteration from the heavy-hitter recognition.Based on statistical theory,analytical expressions about upper-bound error probability were deduced.Simulated results indicate that LRU-BF can achieve space saving and lower error probabilit compared with Naïve-LRU algorithm.Meanwhile,it can also support the 10Gbit/s line-speed processing.…”

Fractional Coins and Fractional Derivatives by J. A. Tenreiro Machado

“…This paper discusses the fundamentals of negative probabilities and fractional calculus. The historical evolution and the main mathematical concepts are discussed, and several analogies between the two apparently unrelated topics are established. …”
